Block's Proto Rig goes retail: one hashboard for $4,187 via Sazmining
Owning a single board of Block's bitcoin miner is now possible without buying the whole machine. Sazmining sells individual immersion hashboards from the Proto Rig, runs them at a new US site and pays the mined Bitcoin straight to the owner's wallet. According to Bitcoin.com News, the purchased boards are expected to start hashing between November and December 2026, so the first owners are only weeks away from their first payouts.
What you get for $4,187
- Hardware: one Proto immersion hashboard, about 204 TH/s at roughly 15 J/TH. Three boards make one Proto Immersion Module, but you can start with one.
- Price: $4,187 per board, either upfront or $1,397 down plus 18 payments of $155 at 0%.
- Running costs: a flat $153 per month for power and maintenance (Sazmining quotes 6.3 cents per kWh), with the first month prepaid at checkout.
- Revenue share: Sazmining keeps 15% of the mined BTC, as Cointicker reports.
- Payouts: the owner picks the pool in the dashboard. With OCEAN, rewards arrive on-chain from each block the pool finds; with Luxor, they accumulate and are sent on a daily, weekly or monthly schedule.
All terms are from the Sazmining Proto page. The company says returns are not guaranteed.
Does it pay at today's hashprice?
On November 1, hashprice on the SHA-256 network was $32.96 per PH/s per day, according to Ziven. By our rough estimate, one 204 TH/s board would earn about $6.70 a day before fees, or around $5.70 after the 15% share. That is roughly $170 a month against the $153 service fee, which leaves very little to pay back the $4,187 board. Higher difficulty or a weaker BTC price would turn that margin negative, and the next halving is about 18 months away.
Sazmining's revenue director Nick Perchey told reporters the company has close to 50 orders, half from new customers, and expects the mined bitcoin to cost about 20% less than spot over the hardware's three-year life. For comparison, KuMining's COO says even a top-end Antminer S23 XP Hyd needs 23 months to break even with free electricity.
Who it suits
The offer is aimed at people who want to own hardware and stack freshly mined sats without noise, heat or a home power bill. It is not a quick-payback product: treat it as a long-term bet on BTC rising faster than difficulty, and run your own numbers before ordering.
